Answer
# 1
8085 microprocessor has a set 5 flip flops which serves as
the status flags & they are : Sign Flag ,Carry Flag,
Auxillary Carry Flag, Parity Flag & Zero Flag

Answer
# 2
there r 5 different types of flags r there.
that is
Sign Flag ,Carry Flag, Auxillary Carry Flag, Parity
Flag & Zero Flag

Ex:
Sign Flag: when the out will come to all zeros that time
zero flag will set.

carrr flag:
the carry flag the more then the eight bits adding
or some other things that carry will come that time the
carry flag will set...

Answer
# 5
zero flag:if result is 0 than it is set condition i.e.1
otherwise it is reset i.e.is 0.
carry flag:if an extra bit arises than it is set condition
i.e.1 otherwise it is reset i.e.is 0.
sign flag:in it only D7 is considered.if D7 is 1 than it
is set condition i.e.1 but if D7 is 0 than it is reset
i.e.is 0.
parity flag:if number of 1's in the answer is even than it
is set condition i.e.1 otherwise it is reset i.e.is 0.
auxilary carry flag:if a carry is generated in D3 & passed
to D4 than ac flag is set condition i.e.1 otherwise it is
reset i.e.is 0.

Answer
# 8
in microprocessor 8085 hav 5 flag register
1.zero flag-if the result is zero then it is set to 1 oter
wise 0
2.parity flag-if in the answer num of 1's is even then then
it set to 1 otherwise 0
3.sign flag
4.auxillury flag-
5.carry flag-if carry is arises then it set to 1 oterwise 0

  Re: What are the different flags in 8085?
Answer
# 10
there are five flip-flop in 8085 which individually denote the characteristic if the ALU result.
1.Sign flag(S): S=1, if D7=1; otherwise S=0;
2.Zero flag(Z): Z=1,if A=00H; otherwise Z=0;
3.Auxiliary flag(AC): AC=1, if a carry is generated from the addition of fourth bit from right of a 8-bit binary no. otherwise AC=0;
4.Parity flag(P): P=1, if A has even parity;
P=0, if A has odd parity;
5.Carry flag(CY): CY=1,Carry is generated;
CY=0,Carry is not generated;
